To @ZZ whomJ t may concern.:

Be it known that I, ALBERT C. RrcHAnDsoN, a citizen of the UnitedStates, residing at South Frankfort, in the county of Benzie and Stateof Michigan, have invented a new and useful Ohurn, of which thefollowing is a specification.

The invention relates to improvements in churns. l

ro The object of the present invention Ais to provide a simple andinexpensive churn capable of readily converting the lacteal Huid intobutter, and of delivering the same upon a suitable plate for convenientremoval.

rlhe invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

2o In the drawings, Figure l is a perspective view of a churn embodyingthe invention. Fig. 2 is a central vertical sectional view. Fig. 3 is asimilar view taken at right angle to Fig. 2.

2 5 Referring to the accompanying drawings, l designates the body of achurn, preferably rectangular in construction7 and mounted upondiagonally-extending legs 2, and having two of its sides provided withpanes of glass 3o 3 to permit the interior of the churn to beinspectedwithout necessitating the removal of the cover 4, and one of the othersides is provided with a thermometer the bulb of which is arranged so asto be in contact with 3 5 the lact-eal fluid to indicate the temperaturethereof, to enable the operator to readily ascertain the proper time andcondition of the lacteal fluid for churning.

Arranged centrallyin the body of the churn 4o and having its lower endstepped in the bottom thereof is a vertical shaft 6, provided withdashers 7, having blades 8, and these rotary dashers 7 act inconjunction with stationary flasher-blades S, mounted upon rods 0,arranged upon opposite sides of the churnbody, and having their lowerends seated in suitable sockets of the bottom, and their u pper endsarranged in perforations of the cover Il, and the said stationary bladesare arranged 5o in the intervals between the rotary blades and above andbelow the latter, and it will readily be seen that this arrangement ofdashers is capable of quickly converting Lacteal fluid into butter by amost thorough and complete agitation of said duid. The upper portion ofthe dasher shaft 6 is provided with a spiral groove lO, adapted to forma screw conveyor to carry the butter as it is formed upward and depositthe same upon a perforated plate l1', extending across the upper 6o partof the churn and provided with a central opening l2 to receive theconveyer portion of the dasher-shaft; and the edges of said plates areprovided with flanges and form a receptacle or dish of that portion ofthe plate between the outer edges or iianges and the central opening l2.The upper end of shaft is provided with a pinion lf3, that meshes with acog-wheel ll, mounted upon the top of the cover and provided with asuitable handle for 7o operating the churn. The upper end of the churnfinds bearing in a central opening of the cover, and the pinion isarranged above the same and is partially housed in a casing l5.

The body of the churn is provided with a suitable bail L16, and thecover is secured to the body in any desirable manner, preferably bymeans which will enable it to be quickly removed when desired. 8o

From the foregoing description and the accompanying drawings theconstruction, operation, and advantages of the invention will be readilyunderstood.

It will be readily seen that the rods 9 may 85 be turned so as topresent the blades 8 at different angles with relation tothe rotarydashers 7 of the central shaft.

Il. In a churn, the combination of the body, 9o the dashershaft havingits lower portion provided with a series of dasher-blades, means foroperating the dasher-shaft and the ad justable dashers, comprising therods oppo' sitely disposed and provided with blades arranged in theintervals formed by the blades of the dashenshaft, and having theirlower ends journaled in the bottom of the body and having their upperends journaled in the cover and projecting above the saine and rooadapted to be turned to adjust tl eblades with relation to the blades oithe dasior, substantially as described.

V2. In a churn, the combination of the body, the dasher-sliaft having'its lowerportion provided With a Series of daslier-blades and its upperportion provided with a spiral groove, means for operating thedaslier-sliaft, the adjustable dashers comprising` the rods oppositelydisposed and provided with blades arranged in the intervals formed bythe blades of the dasher-sllaft, said rods having their loweil endsjournaled in the bottoni of the blades ot' the said rods and providedwith pert'orations, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
